LONG-TERM CREEP AND RUPTURE PROPERTIES OF HEAT RESISTING STEELS AND ALLOYS
LONG-TERM CREEP AND RUPTURE PROPERTIES OF HEATRESISTING STEELS AND ALLOYS

The present status of NRIM Creep Data Sheet Project and the recent activities of long-term creep and rupture studies on heat resisting steels are described. The project has been continued to produce long-term data such as 100 000h-creep rupture strength for 47 kinds of principal heat resisting steels and alloys, including welded joints. The long-term creep deformation behavior and microstructural evolution during creep have been shown to be complicated.
